AUTOMATIC IGNITION CUT OFF Filed Dec. 18, 1937 Patented Mar. 28, 1939 UNITED STATES PATENT OFFICE 1 Claim.

The function of this invention is to cut off 6180-,

trical current in the ignition system of an auto mobile or other conveyance using electrical ignition whenever such automobile is overturned or involved. in a collision. The invention consists of the following:

A flared or funnel shaped housing containing a correspondingly shaped weight; such weight is attached by a flexible cord to a switch.

Referring to the drawing, Figure 1 is a vertical section through the device and Figure 2 is a second vertical section at right angles to Figure 1.

The flared or funnel shaped housing, indicated by l on the drawing, is straight or vertical on the side corresponding to the rear of the vehicle to which it is to be attached, flared at an angle of forty-five degrees on the side corresponding to the front of the vehicle and at an angle of thirty degrees from vertical on its sides. This housing is open at its larger end, which is the upper end, and has a smaller opening suilicient to accommodate the cord at its lower end.

The weight, of metal or other suitable heavy material, indicated by 2 on the drawing, is so shaped as to fit loosely into the housing and corresponds in shape with the housing; it rests upon projections attached to the inner sides of the housing indicated by 3 on the drawing.

The flexible cord, indicated by 4 on the drawing, is attached at one end, to the lower end of 5 the weight, and at the other end, to the electric switch, indicated by 5 on the drawing. Two wires, indicated by 6 on the drawing, one running from the source of the electrical current, and the other to all outlets of that current, are connected 10 by the switch, which upon being thrown by the falling of the weight out of its housing, disconnects the electrical current.

I claim:

A flared or funnel shaped housing, shaped at 15 an angle of forty-five degrees from vertical on one side, of thirty degrees from vertical on two sides, and vertical on one side, open at the top end, containing a weight shaped to fit said housing having a cord attached to the bottom of said 20 weight, which said cord is attached to an electrical switch or cut-off contained in a switch-box attached to the lower end of said housing.
